Yes, the variance in results in huge. I tried all the methods - Dual, Homodyne, Talib, Autocorrelation, Zero Crossings, Phase Accumulation
The results vary significantly with each other and with Zorro. the DominantPeriod can be very different based on what method is chosen. I can confirm that PhaseAccumulation is closest to what Zorro shows but only with about a 70% correlation
